It combines the fast read/write cycle of an SRAM — 45 ns access time — with built-in non-volatile storage, so data is retained at power loss without a backup battery. The 45 ns write cycle time (word/page) matches the access time, meaning the part can be written as fast as it is read, simplifying timing in memory-mapped microcontroller or FPGA designs. ## Package and board-fit: 48-SSOP rework considerations The body is low-profile, and pin 1 is clearly marked on the top, so orientation is unambiguous under magnification. ## Active lifecycle and compliance RoHS3 compliant (2015/863/EU), with no restricted substances above the threshold. The part is available in Tape & Reel (TR) or Cut Tape (CT) options, suiting both high-volume pick-and-place and prototype runs.","metaTitle":"Infineon CY14B101LA-SP45XIT NVSRAM, 1 Mbit, 45 ns, 48-SSOP","metaDescription":"Infineon CY14B101LA-SP45XIT NVSRAM, 1 Mbit, 45 ns access, parallel interface, 2.7-3.6 V, -40 to 85°C, 48-SSOP.

The CY14B101LA is a non-volatile NVSRAM, so the two are not drop-in replacements. A board designed for the CY14B101LA expects non-volatile behavior; substituting a volatile SRAM would require a battery backup or other data-retention scheme."},{"question":"What compliance documentation does Infineon provide for CY14B101LA-SP45XIT?","answer":"The part is RoHS3 compliant (2015/863/EU).
